Table 2. TFF2 serum and urine concentrations as well as fract TFF2 excretion analysed within nephropathies diagnosed in more than 10 patients.

	Glomerulonephritis	Vasc. nephropathy	Diabetic nephropathy
TFF2 serum conc., (ng ml-1)	3.6 (1–10)	9.5 (2–33.3)*	13.5 (4.2–28.1)*
TFF2 urine conc., (ng ml-1)	114.2 (9.5–272.7)	86.2 (23.3–277.3)	90.4 (29.5–286.6)
fract. TFF2 excretion	67.1 (9.6–328)	16.1 (6.8–77.7)*	38.2 (16.6–130.3)

All patients with the given disease were included, Asterisks indicate significant differences in values between vascular nephropathy or diabetic nephropathy as compared to glomerulonephritis (p < 0.01). No significant differences between vascular nephropathy and diabetic nephropathy or within urine concentrations could be found.
